EDGE Analysis
O'Brien was optioned in order to make room for Edwin Escobar starting in Rubby De La Rosa's place in Monday's game against the Astros. O'Brien received one at-bat in his short stint in the majors, for one strikeout. O'Brien has performed well at the Triple-A level in 2016, slashing .306/.330/.601, and could be called up again later in the season.
